Title: Fluid-operated rams
IPC: F15B15/26
Filed: 1971-09-08
Abstract: 1361449 Vacuum operated rams M P GOURNELLE 8 Sept 1971 [8 Sept 1970] 41949/71 Heading F1D [Also in Division B5] A ram piston 18 Fig. 1 is held in its retracted position against a cylinder end-plate 2 by a release means e.g., a solenoid winding 3, against vacuum in a chamber 25, and on de-energizing winding 3 the piston and rod 13 is movedforwardly to its other extreme position by admission of atmospheric air through an electrically operated 2- way valve 6. The forward movement is damped by a resilient stop 24 and the return slow movement is effected by vacuum provided by a pump 9 which is connected through valve 6 and a piston 5 to the winding end of the cylinder. In a modification, Fig. 2 the ram is doubleacting and comprises two spaced piston 27A, 27B on a common rod 28 having notches 47A, 47B engageable with locking keys 48A, 48B. The cylinder chamber 36B between the pistons is continuously open to atmosphere through variable throttles 33A, 33B whilst end chambers 36A, 31B are alternately connected to a vacuum pump 9 and to atmosphere according to the setting of solenoid-actuated valve members 37A, 37B. Cushioning at the ends of the forward and return strokes is effected by piston projections 29A, 29B, entering cavities 30A, 30B which are also continuously open to atmosphere through variable throttles 35A, 35B. The ram rod 28 may be connected to a double stamper or punch whilst ram rod 13 may actuate one or more punches 66 Fig. 4 used to form containers from heated sheets of thermo-plastics material. The punches 66 are carried by a plate 65 having guide rods 64 and are operatively connected to the rod 13 by means of a dashpot 63 comprising a piston 60 rigid with rod 13 and an extension 61 thereof and biased by a return spring 67. Air displaced by piston 60 is forced through channels 70, 71 to the front face of each punch for separating from the punch the formed container and cooling the container. In a further modification the piston is of the vane type and serves to rock a shaft (52) Fig. 3 (not shown).

A right-angled bracket 22, through the horizontal (non-visible) arm of which projects a screw 24, is slidable horizontally by means of a pivot pin 21 engaging slot 20, a wing nut on the threaded pin 21 enabling the bracket to be clamped at any desired angle. A camera is secured on the bracket by means of screw 24 which is equipped with a wing-nut on the underside of the bracket arm for tightening. A pair of wire legs 28 are pivoted at 27, their free ends being bent at right-angles so that when idle they may engage two small holes 29 in the limb 12. The frame may be clamped or held in any orientation, the legs 28, when convenient, being used as a bi-ped.

Abstract: 888,446. Refrigerating. LINDE'S EISMASCHINEN A.G. GES FUR. Dec. 15, 1959 [Dec. 18, 1958], No. 42587/59. Class 29 In a compression system, solvent for the lubricant is added to the refrigerant, the mixed lubricant and solvent being removed. The refrigerant may be ammonia or carbon dioxide and the solvent toluene, trichlorethylene, petroleum, paraffin, white spirit, turpentine or hydraulic oil. As shown, high pressure compressor 10 supplies refrigerant to condenser 12, reducing valve 14 and receiver 8 from which the liquid flows through a second reducing valve 16 to accumulator 2. From the latter the liquid falls through pipe 3 to the bottom of evaporator 1 the vapour from which enters accumulator 2. Vapour from the accumulator is drawn by low pressure compressor 6 which exhausts into receiver 8 and the latter is connected by pipe 9 to the suction of compressor 10. The pressure in evaporator 1 is less than atmospheric and hence solvent is drawn into pipe 3 from open reservoir 21. The mixed solvent and lubricant from pipe 3 enters trap 4 from pipe 3 and can be drawn off by cock 20. Sufficient solvent may be supplied to enter the evaporator to remove lubricant deposits from the walls thereof. Solvent may also be supplied to other parts of the system by pumps 22 . . . 25 and the mixture can be withdrawn from the condenser 12 and receiver 8. The withdrawn mixture can be separated, the components being returned to the system and the separating means may be embodied in the System.

In a frequency measuring apparatus the unknown input is mixed, at 13, 14 with the nth harmonics from two oscillators 10, 11 to yield I.F.'s which are (amplified at 15, 16 and phase compared 17, 18 with a standard frequency, derived from a generator in counter 12, to give outputs which control the phase locking of the associated oscillators 10, 11 and are also connected alternately to a phase lock indicator 19. The output of oscillator 10 tuned to the lower locked frequency is applied to the counter 12 and the outputs of the oscillators 10, 11 are applied to a mixer 21 and frequency halver 22 to providea further input <SP>10</SP>/ n  tothe counter 12 which extends its counting time to count the fundamental frequency of oscillator 10. In order to register a correct count of the input signal a spurious pulse is generated by the counter 12 and added to its tens stage.

Abstract: 1413326 Controlling converters SOC GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES (ALSTHOM) 15 Sept 1972 [29 Sept 1971] 42992/72 Heading H2F A device for pulse-controlling a switching element such as a transistor or a thyristor 1 supplied from a source 38 of periodic voltage and in dependence on a control signal E, comprises an integrator 14 having an amplifier with a capacitor C connected in a negative feedback path, said integrator starting at each passage to zero of the periodic voltage supply 38 and supplying a voltage which is the instantaneous value of the integral of a function of the supply voltage 38, calculated from the starting instant of the integrator 14, and a comparator 7 for receiving at its input that instantaneous value and, directly or indirectly, the said controli signal E and for emitting a switching order for the switching element 1, said integrator 14 being resettable, through a transistor 16 at each passage to zero of the voltage supply 38, to an initial value, to compensate for variations in the supply 38. As shown in Fig. 11, the supply 38 is full-wave rectified at 13, each half-cycle being integrated at 14, the integrator 14 being reset at each passage to zero by a field-effect transistor 16, turned on by transistor 40 at the end of each half-cycle of supply 38. It is shown that the voltage across a load 3 can be proportional to the control signal E and independent of the voltage and frequency of the periodic supply 38 if the integrator 14 is reset at the end of each halfcycle by voltage V which is itself a function of the integral of the voltage of the periodic supply 38. This is obtained from a further integrator 28 which is reset to zero at the end of each halfcycle by means of a field-effect transistor 39. The control signal E is also fed to the first integrator 14 so as to displace its output so that the comparator 7 generates a firing pulse for thyristor 1 at the required time in each cycle. A detailed mathematical treatment is included. In Fig. 18 (not shown) a multiplier is included in series with resistor 18 so as to provide a sin<SP>2</SP> term. Such a circuit is stated to be suitable for use with a thyristor 1, turned on at the appropriate point in each cycle or for a transistor, turned on at the beginning of each cycle and turned off at the appropriate point determined by comparator 7. In Fig. 7 (not shown) control signal E is fed directly to the left-hand terminal of comparator 7, a supply transformer is included having a first secondary feeding the thyristor 1, a second secondary feeding rectifier 13 and a third secondary feeding a further fullwave rectifier which is connected to a CR circuit so as to act as a peak detector which provides a signal to which the integrator 14 is reset at the end of each half-cycle.
